Work on Supercorrections (due Monday, 3/24)
Quiz Wednesday
March 18, 2008
We began by working on Supercorrections. Here are the expectations for these Supercorrections.
Next to your correct solution, write down where the question originally came from. For example, for question 1, it is from homework 8.2, number 3. When you do that, think about why you missed it the second time- had you forgotten how to do it, had you not had a chance to stop by or email about how to do it, did you make a careless error? Include that in your reflections above your solution.
If there is more than one way to do a problem, show multiple methods. For example, on question 9a, you could square the 5 and square the i separately, or you could write out 5i x 5i and then write 5 x 5 x i x i. If you are not sure how to do a problem a second way, just ask!
If there was any possible way of checking your answer, be sure to do so on the Supercorrections. For example, with question 7b, to check your answer, add one, take the square root, and double- is it 5?
In your reflections on the problem, identify the key elements of the problem that are necessary to solve a similar problem in the future. This is your chance to really learn how to do this math- you will see these concepts again, whether it is on a future test, final exam, or future math course.
After working on the Supercorrections, we went over the normal distribution homework on p. 374 and then reviewed how to solve systems of linear equations using p. 294/1, 4-9.

We thought about the following...
For each of the following problems, first estimate an answer and then try to calculate an answer using your mathematical skills.
When was one million seconds ago? How about one billion seconds ago? For more on this problem, click here.
Suppose a string were tied tight around the earth. If one additional meter were added to the string, and the string was lifted the same distance off the surface of the earth, how high would it rise? For more on this problem, click here.
If a piece of paper could be folded in half fifty times, how high would the stack of paper be? For more on this problem, click here.
If you're interested in how we name large numbers, click here.
Read the course methodology and come to class prepared to discuss it (a copy is available on the home page of this website).
Give the parent/guardian letter to your parent/guardian (again, a copy is available on the home page of this website).
Please complete this student information sheet (you won't be able to submit this unless you have all information- including a wikispaces username, parent email address, and textbook number).

March 18, 2008
We began by working on Supercorrections. Here are the expectations for these Supercorrections.- Next to your correct solution, write down where the question originally came from. For example, for question 1, it is from homework 8.2, number 3. When you do that, think about why you missed it the second time- had you forgotten how to do it, had you not had a chance to stop by or email about how to do it, did you make a careless error? Include that in your reflections above your solution.
- If there is more than one way to do a problem, show multiple methods. For example, on question 9a, you could square the 5 and square the i separately, or you could write out 5i x 5i and then write 5 x 5 x i x i. If you are not sure how to do a problem a second way, just ask!
- If there was any possible way of checking your answer, be sure to do so on the Supercorrections. For example, with question 7b, to check your answer, add one, take the square root, and double- is it 5?
- In your reflections on the problem, identify the key elements of the problem that are necessary to solve a similar problem in the future. This is your chance to really learn how to do this math- you will see these concepts again, whether it is on a future test, final exam, or future math course.
